LONDON: Arabica coffee futures on ICE fell sharply on Friday as overnight frosts in top producer Brazil appeared to be less intense and widespread than some had expected and sugar prices also weakened.
September arabica coffee fell by 16.1 cents, or 8.2%, to $1.8040 per lb by 1444 GMT.
Dealers said any overnight damage to trees was unlikely to be as significant as that inflicted by last week's frosts although the health of crops was being assessed.
"The uncertainty over the extent of damage has kept coffee and sugar prices volatile," ING said in a note.
Temperatures dropped across Brazil on Thursday - with rare snowfall overnight in some places - as a polar air mass advanced toward the center-south of the country, threatening coffee and sugarcane crops with frost.
The front month had risen to a peak of $2.1520 on Monday, the highest level in nearly seven years, as last week's strong frosts in Brazil dented the outlook for next year's crop in the world's top producer.
September robusta coffee fell by $94, or 5%, to $1,791 a tonne.
October raw sugar fell by 0.14 cent, or 0.8%, to 18.16 cents per lb.
Dealers were also waiting to see whether overnight temperatures in Brazil were cold enough to cause significant damage to sugarcane crops.
October white sugar fell by $1.90, or 0.4%, to $449.50 a tonne.
December New York cocoa fell by $23, or 0.9%, to $2,462 a tonne.
December London cocoa fell by 2 pounds, or 0.1%, to 1,696 pounds per tonne.
